Existence of Normalized Solutions for Sobolev Critical Fractional Schrödinger–Poisson Systems

We study the existence of normalized solutions for fractional Schrödinger–Poisson systems with doubly critical growth. Under fairly general assumptions on f, with the aid of the Pohozaev manifold and the concentration-compactness principle, we show that there exists a normalized ground state solution for the fractional Schrödinger system when the prescribed mass m is sufficiently large.
